Over the past few months, Internet movie company Vudu has been in the process of morphing from a company that makes a box into a company that (also) licenses its platform to much larger consumer-electronics companies for incorporation into other devices. Yesterday, owners of LG’s BD390 Blu-Ray players got a software update that put the ability to rent and buy movies from Vudu capability on their players. To celebrate, Vudu held a press event at a screening room at Dolby Labs in San Francisco, where it streamed video in its HDX extra-high-quality HD onto a theater screen. It played without hiccups, held up well, and generally helped confirm that Vudu is a neat option for folks who want movies delivered via the Internet without any compromise in visuals or sound.

Also on display at the Dolby event was Mitsubishi’s 52-inch LT-52249 LCD TV with built-in Vudu–a drool-worthy $3099 1080p display that showed off Vudu’s razor-sharp video to impressive advantage. (The Bolt trailer has never looked so good.)

Vudu’s biggest limitation is that unlike humongous archrival iTunes, it’s only available in the living room–not on computers and portable devices. A Vudu representative at the event said that the company said that figuring out how to bring Vudu to more devices is on its to-do list.

The company also announced that Vudu has now integrated Rotten Tomatoes movie reviews into its service’s slick user interface, providing access to a much richer database of critiques as you browse for stuff to watch.
